Blade Trinity R2

[drmih]

Has anybody tried this as it seems to be problematic (I've used 0.86). In quite alot of the movie the results are like a bad vcd. At first I thought it was because I had kept the DTS soundtrack - even then the results were much worse than expected. However, I tried again and dropped the DTS and 2.0 Audio, making the disc size effectively about 6.5 Gb, but the same quality degredation occurred.

Main movie or extras?
If the bad "look" it's only on extras you must check the options you have selected to reduce Extras size, like: "Steal Space from extras" and "Half-D1 and Half Space for Extras" under "Mode" menu.

No it's the main movie disc which only contains the movie with a 5.1 / DTS / 2.0 / 2.0 Commentary 1 / 2.0 Commentary 2 audio tracks and a menu vob of about 200 Mb.

When I first encoded it, I did not remove anything, but the final size came out at 4.8 Gb, even though it was a 3 pass encode. Without checking the quality I used dvdshrink to make it fit but afterwards saw how bad it was and thought it was down to dvdshrink. Therefore I redid it using dvdrb but omitting the DTS and 2.0 audio and this time it did fit the disc correctly. However, the quality problems (massive artifacts and distortion of edges) were still present in the same areas as the first attempt.

Loooks like you're keeping about 1.5 - 1.7gig worth of sound and menu on a high action movie. What's your avg. bitrate, about 3000 kbs? If you must keep all the extra tracks, I'd try running this one through HC. That much action is probably just not giving CCE enough bits to make it happy.

No it's not the amount of audio, there's something going badly wrong. Several of the sequences that break up are reletively stationary - it's not just a typical low bit rate problem, it's more like when you get an 'internet' file which looks okay when very small but is dreadful when blown up. I've run it through dvdshrink now and that's okay and as you would expect for the relative compression. The problem with dvdrb is nearly chapter specific as parts are fine and then dreadful.

You mean, kind of like, since DVD-RB assigns bitrates on a per-cell basis that the problem is almost cell specific in that in the no motion cells(very little bitrate assigned)the picture is not so good, but in the cells assigned a higher bitrate the picture gets better? Hmmm.

[drmih]

No, not that the low motion are bad and the high motion good, it's random. You can have a good low and high motion sequence, or vice versa. It's like there is something confusing the programme. I will try and have a more in depth look but it could be to do with the fact that it's a branching disc and it's where these occur. I came across a similar problem in earlier versions of dvdrb (which then sorted itself out), where whenever you encoded a Network release (a UK company who specialise in classic British tv series), maybe one chapter in 5 would be dreadful. I never identified what the problem was then but used to find the problem chapters and manually encode them with CCE in the D2VAVS directory and then rebuild the disc again.

Do you have the option to encode the extras at a lower quality checked? If so, how much are you dinging the extras? (10%, 25%, 50%) It could be that the scenes that make the extended version extended are being seen as extras. I don't know all that much about this stuff, but it makes sense to me. :D

What bitrates are being applied? Sometimes seamless branching titles can use so much space for the ILVU that there isn't enough bandwidth left to do the remainder of the movie. Since in the current version of DVD-RB the ILVU sections aren't recompressed it could be that what appears to be "random" sections are in fact the sections that are not ILVU...

[drmih]

There are no extras associated with the disc as the movie(s)[the set consists of 43 vobids of which, typically, both the extended and normal versions use about 35 as I remember] are contained within one vob set. However, I do not have the options for the extras selected anyway.

I'll try and identify the problem chapters later but any advice as to what to look for, or information that would be useful would be helpful.

[drmih]

Yes it is the IlVu problem - probably half of the movie has IlVu markers.

In ifoedit there are 23 chapters, made up of 57 cells which are derived from 43 vobids. The ones that are okay, when checked in ifoedit have IlVu next to them, the ones that are bad do not - I haven't checked every single one, but the ones I have all agree with the above.

I did the Blade Trinity Extended Version for North America and had no problems. I watched it all the way through and noticed nothing as far as blocking goes.

Did the R1 Blade Trinity Extended version also have the theatrical version as a branching option?
